WATER-HEATER- Specification of Letters Patent.

Application filed August 10, 1906. Serial No. 329,972.

Patented Jan. 1, 1907.

To all whom it may concern:

Be it known that I, WILLIAM KANE,.0f the city and county of Philadel hia, State of Pennsylvania, have invented an Improvement in Water-Heaters, of which the following is a specification. I

The invention relates particularly to water heaters for producing hot water or steam by the use of gas.

A part of the improvements relate to the construction of the heating-sections which contain the water, whereby great efiiciency is combined with simplicity of construction.

The heater consists of a series of hollow sections or castings provided with hollow lateral parallel projections arranged as to subject the walls of the heater-sections and to improvements in the construction of the burner,

. all of which are more fully described hereinafter.

In the drawings, Figure 1 is an elevation of the heater with one of the halves of the outer casing removed and the top and bottom plates and burner in section. Fig. 2 is a vertical section on the line A A of Fig. 1 with the heater-sections in elevation. Fig. 3 is a plan view of the top plate. Fig. 4 is a perspective view of the burner. Fig. 5 is a perspective view of one of the heater-sections. Fig. 6 is a transverse section of the same on the line B B of Fig. 5; and Fig. 7 is a perspective view of the heater, on a reduced scale, showing its connection with the boiler.

The heater consists of a series of hollow sections a, each formed of a hollow central portion 12, and a series of hollow portions 0, extending laterally on each side and arranged parallel to one another, the end portions being connected with the central portion by short hollow portions (1. These hollow portions 0 are of oblate form and are arranged on edge with their major axes vertical, and thus form intermediate spaces 6 between adjacent sides. The heater is made up of a series of these sections or castings arranged one above the other and connected by suitable couplings f, and successive sections are arranged at substantially right angles to one another, or staggered, so that the lateral portions 0 of successive sections willextend transversely to the corresponding portions of the adjacent sections. The lower section is connected with the supply-pipe g for cold water and the top section with the discharge-pipe h for the hot water. The pipes g and it may be con nected with the ordinary domestic boiler in the usual manner.

The heater-sections a are inclosed in an outer casing, which preferably consists of two vertically-separable halves i i, which may be connected by suitable lugs and fastenings. In Fig. 1 the heater is shown with one of the halves of the casing removed.

The casing-sections are closed at the to as at It, to form the top of the heater, and t 's top is provided with an outlet m for the products of combustion.

n is a top plate located above the heatersections a and having an opening n, through which the pipe h extends. The plate n is supported by a nut n or other support on the pipe and carries on its upper side supporting posts or standards 0 0, on shoulders 0 of which the tops of the casing-sections rest. This plate 1 is provided with slots p, parallel with the portions 0 of the upper heater-sections (1 but such slots are preferably omitted I on the side under the outlet m.

g is a base-plate having a tubular boss g, fitting on and secured to the supply-pipe g,

which closes the base of the heater and forms v the lower support for the casing-sections 1', 1" is the burner, which is located within the heater above the base-plate g and below the I lower section a of the series of heater-sections.

I prefer to employ a burner of the construction shown, consisting of a hollow U- shaped castin'g, each leg being of flattened IOO oval form having perforations s in the top and projections 25 at the extremities, which are adapted to enter sockets t in back casing-section i. The neck and mixing-head r of the burner extends through the frontof the casing and is preferably provided with a lug T, which abuts against the face of the cas- 1ng. When the burner is in place, it embraces the pipe g, as shown, and is preferably arranged with the two legs in a position transverse to the portions 0 of the lower-- heater-section. The products of combustion from the burner 1" pass up within the casing '11 7'. about the heater-sections a, and through the spaces 6 between adjacent portions c. Owing to the construction of the heater-sections, a maximum surface is exposed to the heated products, and by reason of the staggered arrangement of the sections a with reference to one-another the heated products are forced to pass over and in contact with the surfaces 0 c of the successive sections. To prevent a portion of the heated products ascending along the inner walls of the casing, I employ the inwardly-projecting ribs uv on the inner walls of the casing; These ribs are preferably located below the upper heatersections and act to deflect or turn the heated currents inwardly toward the sections. The heated products after passing about the upper heater-section a escape through the slots 1) in the plate n and thence through the outlet m. The slotted plate it acts to restrict the escape of the heated products and to cause them to make proper contact with the walls of the heater-sectlons. The arrangement of the slots p, parallel with the project ing portions 0 of the top section a, creates drafts or currents toward points above the projections, and thus causes the heated currents to pass through the spaces 6 and over the walls of the projections c in seeking the s ots.

While this construction is especially adapted for producing a water-heater, it may also 3 5 be used as a steam-generator, the steam passing out through the'pipe h and the water of condensation returning through the pi e g, and I do not mean to limit myself to the use of the heater for producing hot water.

.What I claim as new is 1. In a water-heater, the combination of a series of hollow communicating sections arranged one above the other and each having a series of lateral hollow projections the hollow projections of one section being arranged at substantially right angles to those of adj acent sections.
